Tires and wheels WARNING
When replacing a tire, make sure you use only the same size,
circumference, construction brand, and load range as the original tires listed on the tire placard. Using other sizes, circumferencesor construction may result in severe mechanical damage to the
drive train of your vehicle and may affect ride, handling, braking,
speedometer/odometer calibration, and clearance between thebody and tires. It also may be dangerous and lead to loss of ve-hicle control. Do not use a combination of radial, belted bias or bias tires
since it may cause dangerous handling characteristics and leadto an accident. Do not let air out of warm tires to adjust pressure. Doing so
will result in low tire pressure.
The tires should b e c hec ked freq uently for p rop er t ire p ressure, wear,
and c uts. Tire pressure
